Ownership THE PATENTS-IN-SUIT: U.S. PATENT NO. 6,629,207; and U.S. PATENT NO. 6,092, United States Patent No. 6,629,207 (the 207 patent), entitled Method for Loading Instructions or Data Into a Locked Way of a Cache Memory, was duly and legally issued to Hitachi on September 30, A copy of the 207 patent is attached as Exhibit A and is made a part of this Complaint. 7. United States Patent No. 6,092,172 (the 172 patent), entitled Data Processor and Data Processing System Having Two Translation Lookaside Buffers, was duly and legally issued to Hitachi on July 18, A copy of the 172 patent is attached as Exhibit B and is made a part of this Complaint. 8. Plaintiff APT is currently the assignee and sole owner of the patents-in-suit (and all worldwide counterparts), including without limitation all rights to sue for past, present and future infringement, including the right to collect and receive any damages, royalties or settlements for such infringements, all rights to sue for injunctive or other equitable relief, and any and all causes of action relating to any inventions of these patents. Brief Summary of the Technology 9. Virtual memory is a memory management technique that allows a program to be designed as though there is only a single hardware memory device (i.e., the virtual single memory device containing logical memory addresses) when, in fact, there may be a plurality of memory devices with portions of each supporting the program (i.e., the physical memory devices containing 2

3 physical memory addresses). Systems that employ virtual memory, among other things, may use physical memory more efficiently and render the programming of applications easier. 10. Computer operating systems that employ virtual memory typically contain a data processor that supports an address translation mechanism in order to translate a logical memory address from the virtual memory (e.g., when requested by a program) into a physical memory address from the physical memory. Such systems may do so by utilizing, among other things, a buffer memory, which may be known as a translation lookaside buffer (TLB). 11. Each of the patents-in-suit discloses data processors that achieve greater processing efficiency through novel and non-obvious improvements to data processor virtual memory structure and operation. INFRINGEMENT OF THE 207 PATENT 12. Plaintiff realleges and incorporates herein by reference the allegations stated in paragraphs 1-11 of this Complaint. 13.
